In the true spirit of One Blockedness, I'm thinking that the major renovation project I'm watching unfold can be the basis for recycled hardscape project in the test garden.
We are redoing the path that runs along our entire grounds. It's cracked and uneven, making it semi-unsafe for anyone with mobility challenges.
Demolished concrete, called urbanite, is often repurposed into the retaining walls for raised beds. Our path is made from painted asphalt. I imagine it'll hold more heat than concrete. Too much heat? Guess we'll find out next year!
